Nasal septal splinting, with an airway incorporated into the splint, has been available since the mid 1970s. Until recently, the airway on the septal splint has been a closed unit. Mucus and blood often accumulate within the airway tube and obstruct the lumen. The new device was designed to provide an open lumen for a longer period of time. A study was designed and completed to compare the open and closed lumens in terms of length of patency. In 71 cases, the same patient had an open lumen splint on one side and a closed lumen splint on the other side, after septal surgery. In 62% of the cases, the open lumen device maintained patency for a longer period of time.
